IMPROVEMENT IN SODA-WATER APPARATUS.

Specification forming part of Letters Patent No. 136,345, dated February25, 1873.

To all whom it may concern:

Be it known that I, JAMES W. TUFTs, of Medford, in the county ofMiddlesex and State of Massachusetts, have invented an Improvement inSoda-Water Apparatus; and I do hereby declare that the following, takenin connection with the drawing which accompanies and forms part of thisspecification, is a description of my invention suflicient to enablethose skilled in the art to practice it.

The invention relates to the arrangement of the conducting-pipes leadinginto or connecting the soda-water cylinders contained in the ice-box orchamber that holds the sirap-containing chambers or cans, and the icethat refrigerates such chambers and the sodawater cylinders.

In my apparatus the sirnp-cans are vertical compartments at the rear ofthe box, having horizontal tubes leading from the cans at or near thebottom of them for drawing the sirups, and in the ice-compartment infront of the cans I place two horizontal soda-water cylinders upon orimmediately over the sirup-conducting pipes, said cylinders beingpreferably in the same plane, and one of them being placed in the frontpart of the ice-chamber,

and the other in the rear part thereof. One

of these cylinders connects with the soda-fountain, and the other withthedraft-cock, and the first cylinder with the other, the connectionsbeing such that the aerated Water enters one end of one cylinder, andpasses through said cylinder and out of its opposite end into a pipeconnecting the two cylinders, and through said connecting-pipe to oneend of the other cylinder, through whose opposite end it passes throughthe outlet-pipe to the draft-cock.

In my invention I utilize the vertical space in the chamber between thetwo cylinders by making the cylinder-connecting pipe in the form of aseries of vertical bends that greatly elongate the connecting-pipe andexpose the soda-water passing through them to the direct cooling actionof the ice placed upon both sides of them and extending between thebends. My invention consists in this arflangement of the pipe connectingthe cylinem.

The drawing represents a case embodying my improved arrangement.

a denotes the box or case, its top being re moved, and its front wallbroken out. b denotes the sirup-containing vessels, arranged in the rearpart of the ice-chamber 0, each vessel b having an outlet ordelivery-pipe d extending from the bottom of its chamber horizontally tothe front of the case. Just in front of the sirup-vessels b and over thepipes cl is a cylinder, 0, into one end of which the charged water leadsthrough an inlet-pipe, f, the water passing through this cylinder andout from its opposite end through a pipe, g, to a similar cylinder, h,placed just in rear of the front wall of the case, the water passingthrough this second cylinder from the end 2', at which it enters to theopposite end from which it flows through the delivery-tube k to thedraftcock at the end of such tube.

Instead of leading the pipe g from the end of the cylinder directly tothe adjacent end of the cylinder, I lengthen the pipe by means of theseries of vertical bends l, which are arranged in line midway betweenthe vessels 0 h, and extending nearly through the vertical space of theice-chamber, these bends being preferably stayed by suitable connectingsup-,

ports m, and being so arranged that the ice will pack closely' againstboth sides of them,

facilitates the cooling of the soda-water, while the pipes occupy butlittle if any space that could be made available for any, other purpose.r

The bends l are shown as extending up between the cylinders e h, locatedupon the pipes d, extending from the sirup-chambers; but thesirup-chambers and their delivery-pipes may, of course, be differentlyarranged.

I claim In combination with the sirup-cans,ice-chamher, and cylinders,all arranged substantially as described, the connecting-pipe, made inthe form of a series of vertical bends, I, located between thecylinders, substantially as shown and described.
